I recently installed Linux Ubuntu on my external drive for dual booting, everything I touched was my external drive. I gave it 8Gb of swap partition and the rest for root. First time installed it worked perfectly, and boot fine.

But after the second boot it just stuck at Grub, I restart computer again and it booted fine, everything worked. But the third time forward it always stuck at grub, can’t boot. How can I fix this problem.

Fist time worked, and second never.

I do this all of the time. LOL. Did you check to see if you have TPM on your system? Secure Boot? That was what prevented me from doing the same thing.

Please copy & paste the pastebin link to the BootInfo summary report ( do not post report), do not run the auto fix till reviewed.Lets see details, use ppa version with your USB installer (2nd option) or any working install, not Boot-Repair ISO https://help.ubuntu.com/community/Boot-Repair But also see this old, but still current bug for installing to external or any second drive. https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1396379 You may have to always have external plugged in, if you do not install grub to external drive.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
